Definitely not BS, so your cosmic egg can remain intact.  In the pan the oil is essentially static, so there is a major boundary layer conduction issue.  In any well designed oil cooler with narrow high-velocity channels with internal fins or turbulators - - Ah-h-h; hold it right there, the AC core doesn’t qualify.  Or are you using a well designed oil cooler? 
 
I'm using an evap core, but I don have a well designed oil cooler or two laying around in the back of the hanger if necessary.   

 

Good luck with your fittings,

 

 Thanks, but it didn't help :-(  I tried a new fitting on the hose, and it still barely leaks, so I guess I falsely accused Earl's, and the problem is really with the fitting that's welded on the evap core.  I just ordered some of those "Del" seals that Spruce sells for this very purpose.  I've heard they work well, but have never needed to use one before.  If they really do require less torque to seal, then they will become standard issue on all my evap core fittings, since I hate to put too much torque when tightening them.  Come to think of it, same goes for the EWP fittings.  Good thing I ordered 20.
